Some banks will annually mail a paper “welcome” letter to all customers purely for the purpose of collecting bounced mail ultimately to verify if anyone has moved without telling them. The letters never state that’s the purpose… they take that opportunity to talk about their service in arbitrary ways. Some banks even charge customers a fee for their cost in doing that. If you ask the banker about it they readily admit that it’s an address verification technique.

That’s it… just a PSA so folks are aware, as it is a bit sneaky.

Some national postal services (e.g. USPS) sell your mail forwarding information which is how you get tracked to your new location by various entities even when you did not inform them of your new address. So obviously a good defensive measure is to never use the mail forwarding service. Select the entities you want to know your new address and inform them directly. But then to get some immunity to the sneaky trick in the 1st paragraph, perhaps give the next resident a stack of addressed envelopes and stamps and ask the next resident to forward (remail) for you… or just ask them to trash your mail instead of returning it.
